The ? character can be used in short codes in the following ways:
Default Short Code Matching
? short codes are used in short code matching in the following way. If no user or system short code match is found, the system will then look for a ? short code match. It will look first for a user ? short code and then, if not found, a system ? short code.
Example: On systems outside North America, the system short code ?/Dial/./0 is added as a default short code. This short code provides a match for any dialing to which there is no other match. Therefore, on systems with this short code, the default is that any unrecognized number will be dialed to Outgoing Line Group 0.
Hot-Line Dialing
A user short code ?D can be used to perform a short code action immediately the user extension goes off-hook. This is supported with Dial type short code features. Typically it is used with door, lift and lobby phones to immediately connect the phone to a number such as the operator or reception.
Voicemail Collect Short Codes
The ? character can appear in the Telephone Number field of a short code. This is done with short codes using the VoicemailCollect feature. In this instance the ? character is not interpreted by the system, it is used by the voicemail server.
